[0002] The stirring mechanism of the reactor is mainly used in production equipment in chemical, pharmaceutical, bio-fermentation and food processing industries that require material mixing, dispersion, dissolution or heat transfer reactions. The reactor usually needs to maintain uniform mixing of materials under heating, cooling and pressure changes. Therefore, the stirring structure must not only achieve effective fluid circulation, but also adapt to the process requirements of different viscosities, different batches and different stages.

[0003] In existing technologies, it is impossible to switch the stirring mode according to the material characteristics and reaction stage requirements. Only a unidirectional stirring action can be achieved, which can easily lead to dead zones in material mixing, making it difficult to ensure mixing uniformity, resulting in poor adaptability and thus affecting reaction efficiency. Utility Model Content

[0004] In view of the above-mentioned problems that existing methods cannot switch the stirring mode according to the material characteristics and reaction stage requirements, can only achieve stirring in one direction, easily lead to dead corners in material mixing, make it difficult to ensure mixing uniformity, have poor adaptability, and thus affect reaction efficiency, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable reaction vessel stirring mechanism, including a reaction structure and a lifting structure and a stirring structure installed on the reaction structure. The stirring structure includes a hollow shaft and a second motor. A first gear is fixedly installed on the motor shaft of the second motor, and a second gear is fixedly installed on the hollow shaft. The second gear and the first gear mesh with each other.

[0006] As a preferred embodiment of the adjustable reactor stirring mechanism of this utility model, the reaction structure includes a reactor and a top cover. The top cover is located at the top of the reactor, and a feed inlet is fixedly provided at the top of the top cover. A guide linear bearing is fixedly provided at the center of the top cover, and a discharge port is provided at the bottom of the reactor.

[0007] As a preferred embodiment of the adjustable reactor stirring mechanism of this utility model, the lifting structure includes a fixed frame, which is fixedly installed on one side of the reactor. A lead screw is rotatably installed inside the fixed frame. A first motor is fixedly installed at the top of the fixed frame. The motor shaft of the first motor is fixedly connected to the lead screw. Guide rails are fixedly installed at both ends of the inner wall of the fixed frame. A sliding plate is threaded onto the lead screw. The two ends of the sliding plate are slidably connected to the guide rails. An mounting plate is fixedly installed on the sliding plate.

[0008] In a preferred embodiment of the adjustable reactor stirring mechanism of this utility model, the hollow shaft is rotatably mounted on the mounting plate, the hollow shaft extends through the guide linear bearing into the interior of the reactor, and is movably connected to the guide linear bearing, and the second motor is fixedly mounted on the top of the mounting plate via a frame.

By rotating the shaft through the turntable, the meshing transmission of the bevel gear and the bevel plate can precisely drive the stirring blade to rotate around the connecting shaft to complete the angle adjustment. After adjustment, it can be re-locked. Different stirring angles can be adapted according to the material characteristics and reaction requirements to effectively improve the uniformity of material mixing. 2. The first motor drives the lead screw to rotate, which in turn drives the mounting plate and the stirring structure to move smoothly up and down. The depth of the stirring structure in the reactor can be flexibly adjusted to adapt to different material depths and stirring depth requirements. This effectively avoids the problem of insufficient stirring caused by changes in the amount of material, and improves the adaptability and flexibility of the stirring structure.

[0015] Example 1 Refer to attached figure Figure 1 - Appendix Figure 3 This is the first embodiment of the present invention, which provides an adjustable reaction vessel stirring mechanism, including a reaction structure 1, a lifting structure 2 and a stirring structure 3.

The top cover 12 is located at the top of the reaction vessel 11. A feed inlet 13 is fixedly provided at the top of the top cover 12. A guide linear bearing 14 is fixedly provided at the center of the top cover 12. A discharge port is provided at the bottom of the reaction vessel 11.

[0016] The lifting structure 2 includes a fixed frame 21, which is fixedly installed on one side of the reactor 11. A lead screw 22 is rotatably installed inside the fixed frame 21. A first motor 23 is fixedly installed at the top of the fixed frame 21. The motor shaft of the first motor 23 is fixedly connected to the lead screw 22. Guide rails 24 are fixedly installed on the inner wall of the fixed frame 21 and at both ends of the lead screw 22. A sliding plate 25 is threaded onto the lead screw 22. Both ends of the sliding plate 25 are slidably connected to the guide rails 24. An mounting plate 26 is fixedly installed on the sliding plate 25.

[0017] During use, the material to be reacted is fed into the reactor 11 through the feed inlet 13. The first motor 23 is started to drive the lead screw 22 to rotate, which drives the slide plate 25 to move up and down along the guide rail 24. Then, the depth of the stirring structure 3 in the reactor 11 is adjusted by the mounting plate 26 to adapt to different material requirements, and the material in the reactor 11 is stirred and mixed. After the reaction is completed, the material is discharged through the discharge port.

[0018] Example 2 Refer to attached figure Figure 3 - Appendix Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: The stirring structure 3 includes a hollow shaft 301 and a second motor 302. The hollow shaft 301 is rotatably mounted on the mounting plate 26. The hollow shaft 301 extends through the guide linear bearing 14 into the interior of the reactor 11 and is movably connected to the guide linear bearing 14. The second motor 302 is fixedly mounted on the top of the mounting plate 26 via a frame. A first gear 303 is fixedly mounted on the motor shaft of the second motor 302. A second gear 304 is fixedly mounted on the top of the hollow shaft 301. The second gear 304 and the first gear 303 mesh with each other. A rotating head 305 is fixedly mounted on the bottom of the hollow shaft 301. A rotating shaft 306 is rotatably mounted inside the hollow shaft 301. The rotating shaft 306 extends through the top of the hollow shaft 301 into the interior of the reactor 11. Above, a bevel gear disk 307 is fixedly installed at the bottom of the rotating shaft 306. Bevel gears 308 are meshed at equal intervals on the bevel gear disk 307. Agitator blades 309 are fixedly installed on the bevel gears 308 through a connecting shaft. The number of agitator blades 309 is set to four.

A turntable is fixedly installed at the top of the rotating shaft 306. A threaded bracket 310 is fixedly installed on the rotating shaft 306 and below the turntable. A screw 311 is threaded on the threaded bracket 310. A friction plate 312 is rotatably installed on the screw 311 and contacts the outer wall of the hollow shaft 301. A rubber pad is provided on the inner side of the friction plate 312 to increase the friction with the hollow shaft 301.

[0019] During use, the rotating screw 311 pushes the friction plate 312 to fit tightly against the outer wall of the hollow shaft 301. The friction is enhanced by the rubber pad to fix the rotating shaft 306. Then, the second motor 302 is started, and its motor shaft drives the first gear 303 to rotate. The meshing transmission between the first gear 303 and the second gear 304 drives the hollow shaft 301 to rotate, which in turn drives the rotating head 305 and the outer stirring blade 309 to make a circular motion around the axis of the hollow shaft 301, and to revolve and stir the material. If it is necessary to adjust the stirring mode, the friction plate 312 can be loosened to fix the hollow shaft 301. The rotating shaft 306 is rotated by the turntable, which drives the bevel gear 307 to rotate. The meshing transmission between the bevel gear 307 and the bevel gear 308 drives the stirring blade 309 to rotate around the connecting shaft, thereby realizing the angle adjustment of the stirring blade 309. After the adjustment is completed, the friction plate 312 and the outer wall of the hollow shaft 301 are tightly fitted together.
